After the strenuous start to the season he's had, Alexis Sanchez could be forgiven for feeling a little fatigued at the moment.

Having played a huge part in Chile's victorious Copa America campaign over the summer, the Arsenal star has thrown himself into the Premier League season with gusto. With Alexis' high-pressing, high-intensity style of play, a bit of tiredness every now and then is inevitable.

But don't say he's tired. Because he's not ruddy tired, okay? He doesn't need a rest. So stop mentioning it, will you?

Sorry to be a bit grumpy about the whole thing, but we're only following Sanchez's lead here. With Arsene Wenger thinking of resting the Chilean forward to stop him from suffering burnout, a lot has been said in England about his fatigue levels in recent weeks. Likewise, after Chile's 1-1 draw with Colombia last week, Uruguayan paper Ovacion claimed that Alexis had put in a low energy performance. That was the last straw for the Gunners' talisman.

He's now responded by posting this clip on Instagram - in it, he asks us all if we're feeling low on energy before generously offering some of his own. That would seem like a pretty kindly offer, if it wasn't followed by a startling and irritable rub of the camera lens. We're assuming it's an attempt to rub the sleep out of our eyes. Because we're the sleepy ones - get it?

Sanchez is clearly feeling a little grumpy over the perception that he's flagging, hence his eagerness to stress that he's actually got excess energy - enough to go around, even. However, as every parent to a small child knows, exaggerated grumpiness is actually the first sign of tiredness. Is it past Sanchez's bedtime? Quite possibly.

From what we've seen here, we recommend a nice mid-season rest. Plus, maybe a nap or two. Then he'll be right as rain.

Sanchez can play more sublime football after he's had a lie down. Believe us, it'll do him the world of good.
